Apologies for asking something that is probably super obvious, i just started with S4 classes and i guess i am not finding documentation that layout the grammar rules and give enough examples. Some questions i am having are these 1. I understand that main method of writing a member function is to write a generic function and setMethod for this particular object. This, however, presumes that there

Hi, I was wondering if anyone has any suggestions for debugging ie- specific errors? I have been working on a porting a prototype application that works fine in firefox to ie, and have run into several problems. For the latest one, the error message is not very informative. When trying to load the application, ie complains "Object doesn''t support this property or method." When

Hey all, Just had a need for this, wondering if it is a candidate for inclusion as it is only a single line and I can''t seem to spot any other way of acheiving the same functionality in less code. String.prototype.isNumeric = function() { return (this.match(/^\d+$/) != null); } I used it in the context of: Event.observe(el,''keypress'',function (e) { if

I am constructing a JSON object that is an array of products. Using a select box, I want to find the object in the array that has an ID that matches the value from the selectedIndex of the select box and return the price. Here is the JSON script: var products = [{''ID'': 16378, ''Cost'': 100.00},{''ID'': 16377,''Cost'':

Hello. I spent an hour or three chasing down a desired effect that mootools implements, namely the simulation of onmouseleave and onmouseenter events. Why? Lets say you have a Menu. A ul element that contains many li elements. If you want to have a function (maybe an effect) fire when the mouse moves outside of the ul, you are out of luck. Observe the mouseout function like so:

Hi again, When you have an ''obeserver'' setup as follows: $(''myForm'').observe(''submit'', validateForm); If a user submits the form the ''validateForm'' function is called and is automagically passed the ''event'' to work with. This is fantastic! But is there a way to pass another argument to the function?

Here''s my problem. Unfortunately I have the need to load up fully qualified html documents into my page. (think tens of thousands of mini sites). I also have the need to be as handicap accessible as possible. (So ajax is essentially out, screen readers aren''t up to snuff yet). Thus I''m using an iframe. The unfortunate part is that I have navigation menus that appear over

Hi there, is it possible to maintain the elements order in DOM when using Effect.Move()? Currently the Move effect will change the element position (using top and left style attrs), this works quite well too, but what I''d like is to change the elements position as well. Consider the following example: html: ... <div id="a">First</div> <div

Hi, i wrote a sliding navigation using effect.morph and effect.appear. I don''t know why but there are a couple of problems: 1. effect.appear seems not to work in IE6 2. The effects aren''t really "smooth". 3. When using effect appear. The new element triggers onmouseover the onmouseout function.... It''s a small script: www.rhizom.nl/volkan/scriptalicous

I have a project for which I used a Wicket template as a starting point. The original example uses prototype.js. I''m using an SVG image as a background and have included a javascript that causes the image to always fill the background, regardless of the client window dimensions. This works fine in Safari 3 (Firefox doesn''t display the background image, but I''ll deal

Hi, I am loading prototype dynamically using the following js: var scr=document.createElement(''script''); scr.setAttribute("type","text/javascript"); scr.setAttribute("src","./static/js/lib/prototype.js"); document.getElementsByTagName("head") [0].appendChild(scr); on IE6

Ive posted this before, but unfortunately I still have yet to resolve it after numerous attempts... Here is the overview: populate a container element with some new html using Element.update and then retrieve the new dimensions of the containig element. Here is a bit of code snippet that I would think should work.. but doesn''t: ==== start snippet ==== <style> .bigBox {

This is way OT, but here goes... I''ve had an iBook for 2 days now and am debugging a web built with prototype/script aculo / windows / etc... I have no real experience on a Mac. Occasionally, there''s no better way to debug JavaScript than an alert in a loop... Once I have the information information I want from the alert, the loop may want to execute another 300 times. I

I''m trying to sort an object by its property names. As I understand it, iterating over an object using for...in or using Hash.each() (or Hash.sortBy()) does not guarantee the order of the properties. Is there an easy and low-overhead way to guarantee order? Or would I need to have some type of collection object that uses arrays instead of the property-value configuration that Hash

Hello, I''m looking for a cross-browsers library based on prototype.js that wraps XML dom. I tried to extend XML dom elements by using Object.extend and Element.extend without success. It works fine with firefox (Object.extend) but don''t work with IE (msxml). I suppose that IE objects are not ''prototype based'' objects. Is there a way to go around this issue like

I am trying to catch failed Ajax requests, but I''m talking about requests that receive no response from the server (server is down), not responses that result in a 500. The latter can be handled with the onException or onFailure callback, but I am not able to handle the former. To reproduce/test: 1) Start your server 2) Create a page that does this:

Hello, I have a little problem with the escape function. Here is my code: function saveData() { new Ajax.Request("post.php", {method:"post", parameters:''message=''+escape(document.getElementById("shoutitmessage").value) } ); } If I have the escape function in my script I can''t post some characters e.g. ä,ö,ü,ß but if
